Question 1 of 5
A patient™s blood pressure elevates to 270/150 mm Hg, and a hypertensive emergency is obvious.
Correct Answer: B
Rationale: In a patient with a hypertensive emergency, rapid and effective blood pressure reduction is crucial to prevent organ damage. The recommendation for IV administration of antihypertensive medications in this scenario is to titrate the medication to achieve a safe reduction in blood pressure, generally targeting a decrease in mean arterial pressure by no more than 25% within the first hour. The specific medication and infusion rate are dependent on the patient's clinical status and individual factors. Therefore, the maximum dose and duration of infusion must be tailored to the patient's response, with close monitoring by healthcare providers. Hence, determining a fixed time for the maximum dose of the drug to be infused is not appropriate in this critical care scenario.
Question 2 of 5
The following inhibits cell wall synthesis, except:
Correct Answer: D
Rationale: Nystatin is an antifungal medication that works by disrupting fungal cell membrane function, specifically targeting ergosterol and causing the formation of pores in the cell membrane, leading to cell death in fungi. It does not inhibit cell wall synthesis, unlike the other options listed.
Question 3 of 5
What is the expected outcome for Valproate?
Correct Answer: D
Rationale: Valproate is an anticonvulsant medication commonly used to treat seizures, epilepsy, and bipolar disorder. It works by increasing levels of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the brain and also affects other neurotransmitters. Therefore, the expected outcome of taking Valproate is to decrease seizure activity by stabilizing abnormal electrical activity in the brain.
Question 4 of 5
A prenatal patient tells the nurse that she is not taking vitamins because she heard that vitamins may cause damage to the fetus if she becomes pregnant. What is the nurse's best response?
Correct Answer: C
Rationale: While vitamins are generally beneficial during pregnancy, excessive doses (megadoses) can be harmful, especially in the first trimester. The nurse should emphasize the importance of taking vitamins at recommended levels and avoiding excessive supplementation. Taking extra vitamins (B) is not advised, and doses above the RDA (D) should be avoided unless prescribed.
